Document restoration method by converged address book server and converged address book client terminal for the document restoration method

Abstract

Provided is a document restoration apparatus and method based on a Converged Address Book (CAB) service, which includes acquiring document change information from a CAB document management server in response to a document restoration request by a client, determining a restoration target document based on the acquired document change information, and restoring a deleted document in the CAB document management server by providing the document restoration request for the determined restoration target document to the CAB document management server. Therefore, it is possible to efficiently manage information relating to a deleted address without a separate auxiliary repository in a CAB server and at the same time, to easily restore an address.

What is claimed is: 
     
         1 . A document restoration method by a Converged Address Book (CAB) server, the document restoration method comprising:
 acquiring document change information from a CAB document management server in response to a document restoration request by a client;   determining a restoration target document based on the acquired document change information; and   restoring a deleted document in the CAB document management server by providing the document restoration request for the determined restoration target document to the CAB document management server.   
     
     
         2 . The document restoration method of  claim 1 , wherein the document change information comprises restoration target document information, included in the document restoration request by the client. 
     
     
         3 . The document restoration method of  claim 1 , wherein the document restoration request by the client comprises at least one of a path of the restoration target document, version information of the restoration target document, and current document version information of the restoration target document. 
     
     
         4 . The document restoration method of  claim 1 , wherein the document restoration request by the client is forwarded to the CAB document management server from the client by using an Extensible Markup Language (XML) Configuration Access Protocol (XCAP) request message. 
     
     
         5 . The document restoration method of  claim 1 , wherein the document restoration request by the client is updated and stored in a CAB Feature Handler (FH) Application Usage of the CAB document management server. 
     
     
         6 . The document restoration method of  claim 1 , further comprising providing, by the CAB server, document version information of a deleted document to the client in response to the document restoration request by the client. 
     
     
         7 . The document restoration method of  claim 1 , further comprising upon receiving a response message from the CAB document management server after completed restoration of a deleted document in the CAB document management server, storing a document restoration result in the CAB document management server. 
     
     
         8 . The document restoration method of  claim 7 , further comprising upon receiving a response message regarding storage of the document restoration result from the CAB document management server, transmitting a notification message for document synchronization to the client. 
     
     
         9 . The document restoration method of  claim 1 , wherein the document restoration request for the determined restoration target document comprises at least one of a path of the restoration target document, current document version information of the restoration target document, and document version information to be restored of the restoration target document. 
     
     
         10 . The document restoration method of  claim 1 , wherein the document restoration request for the determined restoration target document is forwarded to the CAB document management server by using an Extensible Markup Language (XML) Document Command Protocol (XDCP) request message. 
     
     
         11 . A Converged Address Book (CAB) client terminal for document restoration, the CAB client terminal comprising:
 a storage unit for storing a deleted-document list comprising version information of at least one deleted document; and   a controller for acquiring version information of the at least one deleted document from a CAB server upon a document deletion request, storing the acquired version information, and upon selection of a restoration target document from the stored deleted-document list, transmitting a document restoration request to the CAB document management server for the CAB server to restore the selected restoration target document in the CAB document management server.   
     
     
         12 . The CAB client terminal of  claim 11 , wherein the document restoration request comprises at least one of a path of the restoration target document, version information of the restoration target document, and current document version information of the restoration target document. 
     
     
         13 . The CAB client terminal of  claim 11 , wherein the document restoration request is forwarded to the CAB document management server by using an Extensible Markup Language (XML) Configuration Access Protocol (XCAP) request message. 
     
     
         14 . The CAB client terminal of  claim 13 , wherein the document restoration request is updated and stored in a CAB Feature Handler (FH) Application Usage of the CAB document management server. 
     
     
         15 . The CAB client terminal of  claim 11 , wherein the controller, when using a Data Synchronization (DS) protocol message, forwards a document replacement request to the CAB server to restore the selected restoration target document. 
     
     
         16 . The CAB client terminal of  claim 15 , wherein the document replacement request comprises at least one of a path of the restoration target document, current document version information of the restoration target document, and document version information to be restored of the restoration target document.
